First of all, let’s start with different examples

imagine you have to pay 2 dollars for each cookie

[native igloo]

Ok

[heavy oasis]

if you want to buy 3 cookies, how much do you have to pay?

[native igloo]

6

[heavy oasis]

exactly!

[native igloo]

WAIT OH

[heavy oasis]

Now what about if you want to buy 2.5 cookies?

[native igloo]

5?

[heavy oasis]

Yes!

[native igloo]

Oh wait ok I get it now

Ty dude

[heavy oasis]

[heavy oasis]

ok before you close the forum lemme send one thing

[supple hound]

So what answer did you get

[native igloo]

Y=4 over 145 x 400

I checked the back if the book it said the answer was right

[supple hound]

Are you sure that’s the same answer as the problem you gave us

[heavy oasis]

Not to interrupt, but this is the general form

For the cookies example:

You obviously shouldn’t write those things so basically this is what we have:

[supple hound]

Ok but like

290 miles takes 8 gallons of gas so how many gallons would it take to travel 400 miles

[heavy oasis]

Lemme check

[heavy oasis]

Yes

so what’s the problem?

[supple hound]

You can’t show a pic of the problem

[heavy oasis]

he said 4/145 which is the same as 8/290

[supple hound]

Oh the x is times

I thought that was a variable

Threw me off

[heavy oasis]

oh lol
